-Be 1t known 'that-IKRrs"r1AN LYE, sergeant, a citizen of Norway,resi-ding at Opheimsgaden 69,y Stavanger, Norway, lhave invented newandV useful Improvements '1n Opening Devices -forCan s, of which thefollowing is a s pecil'ication.' l

I My present invention relates p to' nnprovements in opening devices4for censor boxes adapted to contain preserved fruit, snuff, to-

bacco, etc. The opening device forming'the object of this invention'isequally applicable to round, rectangular, oval or otherwise formed cans.Further my opening device i's of such a kind, that soldering can bethoroughly-dispensed with. 'lhe accompanying drawing illustrates by wayof examplejsome forms-of the present opening device. l l Figure 1 is aside view of box body and cover beforethe parts have been foldedtogether. Fig. 2 is a plan view of the boxbody shown in Fig'. 1. Figs. 3and 4; are sid'e view and plan view of the'boxlin a ready state. Fig. 5is a section on the line 1-1, Fig. .4.

Fig. 6 is a section on the line 2-.-2, Fig. 4.

Fig. i5.\a section Icorresponding toFig. 6 vshowmgthe parts after theopening has `begun. Fig. S is. aplan view showing a r'nodiiiedarrangement of the opening lines. Fig. 9 section on .the line 3 3, Fig.8, and Fig. 10 is a plan view corresponding to Fig. 8 and showing theparts after the opening has begun. l

The box body -c is pressed out with an upperilange '-6- tuined outwards(Fig. .1),

[and corresponding thereto the cover -chas a seam flange' At a suitableplace of the rlanga-t.- is arranged an extension or opening ha,-i-cintegral-with the flange -b--, andprefe'rably around the root ofsaivd lip weakening lines -fare provided `in the sheet material.

together in the manner illustrated in Fig. 5.

l During this` folding the inner part of the lip trated in Fig. 6, whilethe -outer part of thelip projects outfroni the seam, see Fig. 6.

When the box shall be opened thelip --eis caught in usual manner by theopening key and rolled around the same.. Hereby the'inner endl of thelip is pulled out Afrom the seam and the llange material clof the coverisat the Sametime torn out at Sipecic-ation 'of Letters Patent. l IAlipplicration filed .Tune 12', 41907.- Serial No. 378,550.

the pm, into which the lips located. said part ofthe material- -d-- isthus coiled to.

gether with -the lip around the opening key. vWhen now the lip is quiteseparated from the box body along the lines. -fthe materials '-eand-dhave been .coiled so lrmlytogether, that theurther opening (see Fig.7) will take place, as if the coiled partsfcand -dwere integral, thematerial o f the cover being separated along the weakening'linesx-g-(Fig. 4).

In order that the contents -of the box may .be laid completely open, thedevice may be' arranged as illustrated' in Figs. 8-10, in" .which thelip. -e'-'- is arranged in a corner of a rectangular box,the cover ofwhich is provided with: two parallel weakening lines J1/ whereby not thewhole cover, but only -the strip -filocated between the lines *ltiscoiled 'around the opening key ,-cas illustrated in Fig. 10. When thisstrip. i has been tornout all around the cover, the box can be easilyemptied by turning it over. l I

. Having now described my invention, what I claim as new and desire tosecure by Letters Patent is 1. The combination with-a box body having anupper seaming flange, and a lip forming at a suitable vplace anextension of said `flange, ofweakening lines arranged around 'the rootof the lip7 .a coverv provided with a corresponding seaming flangefolded togetherwith the llange' of the box body in order to hermeticallyseal the box, weakening lines arranged in, the cover beginning at theinner end of the'lip and passing near the with the flange of the boxbody in order 'to 'Y hermetically seal the box, two parallel weakeninglines arranged in the cover beginning at the inner end of the lip andfollowing round the box the outer of said parallel weakening lines beinglocated above the Patented Dee.
